What these guides cover
Mental rotation is the ability to imagine how an object looks after it turns in space. Spatial reasoning practice goes wider: it includes tracking structure, rejecting mirror errors, predicting motion, and staying accurate under time pressure.
The app gives you a fast way to train those pieces, but the pages below explain how to use it deliberately instead of just clicking through rounds.
Best path for new users
- Use the mental rotation test page to set a baseline.
- Spend a few minutes in the rotation lab to study the shapes.
- Move into the practice guide and build a short weekly routine.
